Statistical analysis was performed with Student’s We performed a knockdown experiment using siRNAs targeting LSD1, and tranylcypromine, a chemical inhibitor for LSD1 (Karytinos gene Given that inhibition of LSD1 accompanied by upregulation of CDH-1 and downregulation of invasiveness of colon cancer, we speculated that LSD1 can promote metastasis of colon cancer by downregulating CDH-1 expression. cancer cells. The LSD1 antagonists might be a useful strategy to suppress metastasis of colon cancer. promoter and repressing transcription, which requires confirmation by further experiments. Therefore, we attempted to investigate the expression of LSD1, CDH-1 and CDH-2 (N-cadherin) in several colon cancer cell lines, and to analyse their relationship with proliferation and invasion abilities of colon cancer, we also aimed to determine the mechanism of colon cancer metastasis regulated by LSD1. Material and methods Immunohistochemical staining The archival formalin-fixed and paraffin wax-embedded tissue blocks of 108 colon cancer and 30 normal colon mucosa removed by surgery from 2006 to 2008 were retrieved from the Department of Pathology, Xiangya Hospital, Central South University. Primary antibodies were directed towards LSD1 (rabbit monoclonal, 1?:?100; R&D Systems, Minneapolis, MN, USA). Serial sections of 5?promoter for ChIP were as follows: F: 5-AGTCCCACAACAGCATAGGG-3, R: 5-TTCTGAACTCAGGCGATCCT-3. Sheared genomic DNA was used like a positive control (input) and for the normalisation of DNA immunoprecipitated by LSD1. Statistical analysis Statistical analysis was performed using SPSS software (version 17.0; SPSS Inc., Chicago, IL, USA). Statistical analysis was performed with Student’s We performed a knockdown experiment using siRNAs focusing on LSD1, and tranylcypromine, a chemical inhibitor for LSD1 (Karytinos gene Given that inhibition of LSD1 accompanied by upregulation of CDH-1 and downregulation of invasiveness of colon cancer, we speculated that LSD1 can promote metastasis of colon cancer by downregulating CDH-1 manifestation. To assess whether the promoter of is definitely directly controlled by LSD1, which as a result would lead to an enrichment of activating histone marks, ChIP analysis was performed using anti-LSD1 and anti-H3K4m2 antibodies in SW620 cells, LSD1-silenced SW620 cells and tranylcypromine-treated SW620 cells (transfected with siLSD#2 or treated with tranylcypromine for 48?h). The results confirmed that LSD1 is present in the proximal promoter of in cells of all the three organizations, and quantitative analysis revealed the enrichment of LSD1 in the proximal promoter of was significantly higher in SW620 and tranylcypromine-treated SW620 cells than in LSD1-silenced SW620 cells (Number 4ACC), which was in accordance with invasiveness of SW620 cells and LSD1-silenced SW620 cells, but was inconsistent with invasiveness of tranylcypromine-treated SW620 cells. We further investigate whether tranylcypromine affected the enzymatic activity of LSD1. Open in a separate window Number 4 LSD1 reduces H3K4 dimethylation in the promoter of (immunoprecipitated with anti-LSD1) was significantly reduced LSD1-silenced SW620 cells than in SW620 cells and tranylcypromine-treated SW620 cells. (D and E) The level of H3K4m2 in the promoter of the gene in LSD1-silenced SW620 cells and tranylcypromine- treated SW620 cells was significantly higher than that in SW620 cells. Ideals symbolize meanstandard deviation of three self-employed experiments. Both di- and tri-methylated H3K4 are associated with active transcription (Kouzarides, 2007; Li gene in LSD1-silenced SW620 cells and tranylcypromine-treated SW620 cells, and a significant decrease in this active mark specifically in the promoter region in SW620 cells (Number 4D and E). Consequently, we conclude the manifestation of LSD1 prospects to a specific decrease in H3K4m2 at promoters, downregulates the CDH-1 manifestation, and as a result contributes to colon cancer metastasis; Tranylcypromine cannot downregulate the protein level, but suppress the enzymatic activity of LSD1 in the proximal promoter of promoter.
